I have removed my dpf, swirl vanes, egr and remap. Mostly in the name of longevity or to solve issues. Inevitably you solve one issue but create another. I have seen dyno prints around 290 for the 330d with dpf still in place. I would be tempted to leave it all as it is for the time being. Unless you have a dyno map it can be slightly awkward getting a map for a car with lots of bits missing.
